Lycee Schorge Secondary School in Koudougou, Burkina Faso
- 2. Project Name: Lycee Schorge Secondary School Location: Koudougou,Burkina Faso Architects: Kéré Architecture Area : 1660 m² Year : 2014- 2016 Client : Stern Stewart Institute & Friends INTRODUCTION
- 3. Located on the outskirts of Koudougou, the third most populated city of Burkina Faso, the new Lycée Schorge building draws inspiration from traditional settlements in this part of West Africa, offering reinterpretations of vernacular building materials and systems on a contemporary note. CONCEPT
- 4. Covering 1660sqm, the school features a unique courtyard layout and a suite of local materials that is both practical and efficient in terms of cost and function. The impressive use of these materials and the peculiar design of the building (roofs and wind towers), aids cross ventilation as well as the penetration of natural light which ensure the comfort of the students within the building. CONCEPT
- 5. PLAN The school consists of nine modules arranged radially around a courtyard, which accommodate a series of classrooms and administration rooms. A series of steps creates a loosely defined amphitheater. The modules, each 900 square feet, contain classrooms and offices, along with a dental clinic. Admin area Dental Clinic Classrooms
- 8. WALLS The walls of these modules are made from locally-harvested laterite stone. When the stone is left exposed to the sun, it begins to harden. The material functions really well as a wall system for the classrooms because of its thermal mass capabilities, absorbing the heavy daytime heat and radiating it at night.
- 9. ROOF The main element of the building is a large metallic roof which protects the laterite stone architecture from the strong African sun and enables the circulation of air beneath.
- 10. FACADE A secondary façade made of local eucalyptus wood wraps around the classrooms like a transparent fabric and creates a variety of shaded spaces. The screens not only function to protect the earthen classrooms from corroding dust and winds, they also help to create a series of secondary informal gathering spaces for the students as they wait to attend their classes. In these spaces, the organic vertical elements produce a stunning play of light.
- 11. FACADE The masonry facades are punctuated with tall, unglazed windows covered with colorful metal shutters, which bring light and air into the building. Curved seating units made of thin wood members are affixed to the window casings and appear to merge with the shutters.
- 12. CEILING One of the major factor that helps to naturally ventilate and illuminate the interiors is a massive undulating ceiling. The wave-like pattern of plaster and concrete components are slightly offset from each other, diffuse indirect sunlight in order to improve the light quality while avoiding the heat otherwise caused by direct radiation. The undulating ceilings are made of gypsum fiberboard, straw, and cement mortar. Long slits in the cream-colored surfaces allow the classrooms to breathe and expel heat while ushering in diffused daylight.
- 13. On the outer façade, the window shutters transform into curved seating elements made of wood, which provide comfortable rest corners. These seats cover the concrete tunnels inserted into the lower side of the windows for ventilation. The same concrete tunnels project more from the façade to become the seating elements on the inner façade. These projecting elements break the two-dimensional verticality and bring a dynamic configuration to the facades. WINDOWS
- 14. WIND TOWERS Wind towers located at the back of each classroom allow hot air to escape, thus helping to further lower the interior temperature. The sculptural forms of these towers stand out above the main body of the building, creating a landmark in its surroundings. To further enhance the indoor climate, Kéré added a series of angular, 8-foot- high concrete wind towers that capture fresh air and funnel it downward. The building features wind-catching towers planted on top of the classrooms to enable air flow in out of the classes.
- 15. FURNITURE In order to maximize the material transported to the site, the school furniture inside the classrooms is made from local hardwoods and leftover elements from the main building construction such as steel scraps from the roof. In this way, the economy of the building is extended by reducing waste adding additional value to the cost of construction.

- 21. CONCLUSION This design not only functions as a marker in the landscape, it is also a testament to how local materials, in combination with creativity and team- work, can be transformed into something significant with profound lasting effects. The amalgamation of traditional architecture and culture with technology is evident throughout the building, making its space comfortable and malleable to people’s needs and requirements.
- 22. CONCLUSION The classrooms have been conceived according to very simple cross ventilation and shading principles, with no use of active engineering elements. The main element of the building is a large metallic roof which protects the laterite stone architecture from the strong African sun and enables the circulation of air beneath.
